Developing a medical device-grade T₂ phantom optimized for myocardial T₂ mapping by cardiovascular magnetic resonance.

ABSTRACT:

Introduction

A long T₂ relaxation time can reflect oedema, and myocardial inflammation when combined with increased plasma troponin levels. Cardiovascular magnetic resonance (CMR) T₂ mapping therefore has potential to provide a key diagnostic and prognostic biomarkers. However, T₂ varies by scanner, software, and sequence, highlighting the need for standardization and for a quality assurance system for T₂ mapping in CMR.

Aim

To fabricate and assess a phantom dedicated to the quality assurance of T₂ mapping in CMR.

Method

A T₂ mapping phantom was manufactured to contain 9 T₁ and T₂ (T₁|T₂) tubes to mimic clinically relevant native and post-contrast T₂
